FEEDING DEVICE FOR GRASS-TWINE MACHINES.

To all whom it may concern:

Be it known that I, EDWARD W. Goonmck, residing in Oshkosh, in thecounty of W nnebago and State of Wisconsin, have 1nvented new and usefulImprovements in Feeding Devices for Grass-Twine Machines, of which thefollowing is a description, reference being bad to the accompanyingdrawings, which are a part of this specification.

This invention relates to improvements in feeding devices particularlyadapted for feeding grass twine in a continuous stream to the thread orcord wrapping mechanism of a grass twine machine.

It is-one of the objects of this invention to provide a feeding devicefor grass twine machines which is adapted to feed grass or othermaterial of varying lengths and thicknesses in a continuous stream ofsubstantially the same diameter.

A further object of this invention is to provide a feeding device forgrass twine machines in which the grass or other like material isdischarged substantially vertically frcm the device.

A further object of this invention is to provide a feeding device forgrass twine machines which is adapted to be oscillated by means of awrist pin or cranked connection with a rotary member.

With the above and other objects in view, the invention consists of thefeeding device and its parts and combinations as set forth in theclaims, and all equivalent thereof.

In the accompanying drawing, in which the same reference charactersindicate the same parts in the view: the figure of the drawing is a sideview of a fragment of a grass twine machine provided with the improvedfeeding device, portions of both the feeding device and the grass twinemachine being 1n section.

Referring to the drawing the numeral 5 indicates the frame of the grasstwine machine and 6,the thread or cord wrapping mechanism mountedthereon which may be of any ordinary construction. A vibrator shaft 7provided with a disk Shaving a wrist pin 9 extending therefrom isournaled on the main frame and is adapted to oscillate or vibrate acombined rass holder and feeder 10 pivotally mounte on the frame 5. Thefree end of this holder is provided with Specification of LettersPatent.

a projecting pin 11 which is pivotally connected to the wrist pin of thevibrating shaft 7 by means of a connecting link 12. The openings of theconnecting link through which the pins extend are of sufficient size topermit the oscillation of the holder without binding. The holder 10consists of a circular receptacle 13 having a conical bottom portion 14provided with a feed or discharge aperture 15 at its vortex ofsufficient size to permit several lengths of grass or other material topass through it at the same time. The angle of the bottom port-ionadjacent to the discharge aperture is increased as indicated by thenumeral 16 in order to expedite the movement of the grass or othermaterial toward the discharge aperture. The aperture 15 is provided atthe lowest point of the bottom portion so that when the holder isvibrated by the vibrator shaft 7 the lengths of grass in the holder willwork down toward the aperture and pass therethrough in a continuousstream. The side portions of the holder are provided with upstandingspring rods 17 carrying guards 18 on their upper ends which serve tohold the lengths of grass in vertical position and yield suflicientlysidewise to permit the grass to be forced between the guards in chargingthe holder.

A pair of draw feed rollers 19 rotatably journaled on the frame 5 andpositioned immediately beneath the aperture of the receptacle andbetween the receptacle and the thread or cord wrapping mechanism, areadapted to draw the grass or other material away from the receptacle andfeed it to the wrapping mechanism positioned beneath the rollers. Thefeed rollers may be rotated in any manner desired.

While the tubular shaft is shown positioned in vertical axial alinementwith the aperture of the receptacle the receptacle is adapted to feedmaterial to wrapping mechanisms in which the tubular shaft is in ahorizontal position by having the material pass partly around one of thefeed rollers before entering the tubular shaft.

In the operation of the feeding device marsh or other grass is placed onthe holder with the butt ends resting on the conical bottom portion ofthe receptacle or holder. The rotation of the vibrator shaft causes therapid vibration or oscillation of the rass holder and the grasscontained thereln to work down the incline of the conical bottom portionand pass out through the aperture in a continuous stream of overlappinglengths of grass which pass between the draw feed rollers. The draw feedrollers will exert a pull on the stream of material and compress andfeed it to the wrapping mechanism which will wrap thread or cordtherearound and form a continuous twine of grass. As the aperture of theholder is of sufiicient size to permit the passage therethrough ofseveral-lengths of grass at the same time and as the lengths of grasstaper to a less diameter toward their tops the lengths of grass will bedischarged in sue-- cessive order and overlap each other and breakjoints. As the butt ends of the grass cannot pass through except insuccessive order due to thegra'dual taper of each length of grass aregular even feed of material to the wrapping mechanism is provided for.

While the feed device shown and described is adapted to form a twine ofa given size it is obvious that holders with different sized aperturemay be provided to form twine of various sizes.

From the foregoing description it will be seen that a grass twinefeeding device is provided which is very simple in construction andoperation and is well adapted to feed a continuous stream of material ofvarious lengths and diameters to the wrap ping mechanism.

lVhat I claim as my invention is:

1. A feeding device for grass twine machines, comprising a materialholder consisting of a receptacle having a conical bottom portionprovided with an aperture at its vortex through which the material isdischarged, said holder adapted to hold material extending in a verticaldirection with the lower ends of the material resting on the inclinedbottom portion, draw rollers positioned immediately beneath the conicalbottom portion, and means forvibrating the receptacle.

2. A feeding device for grass twine machines, comprising amaterialholder consisting of a receptacle having a conical bottom portionprovided with an aperture at its vortex through which the material isdis: charged, the taper of said bottom portion increasing toward theaperture, and means for vlbrating said receptacle.

{3. A feeding device for grass twine machlnes, comprislng a materialholder consisting of a receptacle having a conical bottom portionprovided with an aperture at its vortex through which the material isdischarged, the taper of said bottom portion increasing toward theaperture, means for drawing material through the aperture, and means forvibratingsaid receptacle.

4. A feeding device for grass twine machines, comprising a materialholder consisting of a receptacle having a conical bottom portionprovided with an aperture at its vortex throughwhich the material isdischarged, the taper of said bottom portionincreasing toward theaperture, draw rollers for drawing material through the aperture, andcrank means for vibrating the receptacle.

5. A feeding devicefor grass twine machines, comprising a materialholder consisting of a receptacle having a conical bottom portionprovided 'with an aperture at its vortex through which the material isdis charged, a crank shaft, and a link connection between the crankportion of. the shaft and the holder.

6. A feeding device for grass twine machines, comprising a materialholder consisting of a receptacle having a conical bottom portionprovided with an aperture at its vortex through which the 'material isdischarged, a crank shaft, a link connection between the crank portionof the shaft and the holder, and draw rollers positioned beneath thereceptacles.

7. A feeding device for grass twine machines, comprising a pivotedmaterial holder provided with a conical bottom portion having anaperture at its vortex through which the material is discharged, thetaper of said bottom portion increasing toward the aperture, a crankshaft,.a link connecting the crank portion of the shaft to the holder,and draw rollers positioned beneath the conical bottom portion.

8. A feeding device for grass twine ma-' chines, comprising a frame, apivoted material holder provlded with a conical bottom portion having anaperture at its vortex through which the material is discharged,

with a disk having a wrist pin extending therefrom, a link connectionbetween the wrist pin and the material holder, and draw rollerspositioned beneath the conical bottom portion.

In testimony whereof, I affix my signature, in presence of twowitnesses.
